How To Move USB BTD Content To A New Server

I have ServerA running BE2010 R3.  I have a USB RDX drive that is running BTD jobs with no problem.

I would like to test disaster recovery, so I have installed BE2010 R3 on ServerB. 

How do I restore data backed up onto the RDX onto ServerB?

I tried to add a removable folder on ServerB (as I set it up originally on ServerA), but it sees it and says the a folder already exists.
